Abstract: 1,089,668. Television. WESTINGHOUSE ELECTRIC CORTORATION. May 11, 1965 [June 1, 1964], No. 19842/65. Heading H4F. [Also in Division G5] A teaching apparatus comprises a storage means including e.g. stereo phonograph record or stereo magnetic tape for audio and video information, an audio selecting and reproducing means, a video monitor, e.g. a television set, and a storage and converting means for the video information, which latter means receives from the storage means the video information on a recording medium at a predetermined speed (e.g. below the persistence of vision), and reads stored video information at a higher predetermined speed (e.g. above the persistence of vision). The embodiment of Fig. 5 includes two storage and converting means in the form of magnetic recording drums 40, 42, and two read and write heads 44, 46 associated therewith. The drums are fast on sleeves 90, 92 slidable along a drive shaft 74 so that the drums may be engaged respectively with clutches 70 or 76, 78 or 72. The clutches 76, 78 are driven at a low speed via gear train 79 and rotatable sleeve 88, whilst high speed clutches 70, 72 are driven directly by the shaft. A switch 50 is so arranged that one head (46) is writing information on one drum (42) whilst the information on the other drum is being read and passed to the video monitor. The video information may be passed through electrical-optical converting means, to optical-electrical converting and storage means (Fig. 2, not shown). The converting and storage means (Fig. 3, not shown) may comprise two electron guns (writing and reading guns) which are diametrically opposed and which impinge an electron beam upon opposite sides of a target structure. Question and answer.-The storage medium for the audio and video information has audio and video tracks thereon so arranged that when the initial video picture is being viewed the corresponding audio information will be presented. The second video picture, which has been recorded by the storage and converting means during showing of the first video picture, is then shown and it may comprise a question and three possible answers. A student, upon selecting an answer, is connected to one of three tracks (each corresponding to an answer), which provides additional or remedial instructions.

Material calcined in a cyclone furnace 1 is fed through a cooler 2 with the waste gases, before the gases are passed to a raw-material pre-heater 4. In one embodiment, Fig. 1, the pre-heater 4 is a coiled tube heat exchanger, and the calcined material and gases are fed through the heat exchanger to dust filters 5, clean gases being extracted by a fan 6, and the material being discharged to a conveyer 12. The raw materials from a hopper 13 are fed pneumatically through the heat exchanger 4 to a horizontal cyclone furnace 1, which receives pre-heated combustion air from the outer jacket 3 of the cooler 2. In a modification (Fig. 2, not shown) the calcined material and gases are fed from a vertical cyclone furnace (1) through the air jacketed cooler (2) to a series of cyclones 4<SP>1</SP>. The lower cyclones form further coolers for the calcined materials, and partially pre-heat the air from a fan (7) passing to the jacket (3) of the cooler (2).

Abstract: 602,892. Road-vehicle resilient suspensions. SOC. DE CONSTRUCTIONS MECANIQUES CHENARD & WALCKER. Aug. 7, 1945, No. 20178. Convention date, Jan. 31, 1941. [Classes 108 (ii) and 108 (iii)] A vehicle suspension comprises a bundle of prismatic torsion bars secured to the vehicle frame and to a crank supporting a stub axle, the crank journal being mounted in a bearing which is rigidly secured to the frame and is provided on its inner surface with a lining having a high friction factor. In the construction shown a torsion bar 1 comprises a cluster of rectangular or hexagonal crosssectioned constituent bars a secured by a strap 1a, and extends the full width of the vehicle, being anchored centrally by a bushing 3 which is internally machined to fit the polygonal contour of the bar. The boss 7a of an arm 7 carrying each stub axle 15 is secured to each outer end of the torsion bar 1 by means of a screwed extension on a sleeve 6, the internal surface of which is also machined to fit the bar 1. The boss 7a is journalled in a bearing 11 bolted to the chassis 14 and having a bush 12 of friction material, the damping effect of which depends upon the axle loading and supplements the damping produced by the friction of the constituent bars a. A tube 20 surrounding the bars 1 is rigidly secured to the outer surface of the sleeve 6 and is rotatably carried at its other end by the bushing 3. The initial setting of the arm 7 may be arranged to be horizontal so that the moment arm of the wheel reaction about the torsion bar decreases with increasing deflection to give a suspension of increasing hardness. In an alternative construction the constituent rods a may be arranged to surround a central mandrel or tube and may have an initial helical twist.

Abstract: 862,965. Pressure-sensitive adhesive tape. POLYPLASTIC. June 27, 1957 [June 27, 1956], No. 20306/57. Class 140. A pressure-sensitive adhesive material is produced by applying in a single operation to a support, a coating consisting of a mixture of an adhesive substance and a film generating product which serves to retain the adhesive on the support, the latter product being applied in the form of an aqueous solution or emulsion, the film generating product being such that the mixture adheres to the support when applied thereto as an aqueous solution or emulsion with a greater adhesive power than when it comes into contact with the support after evaporation of the water. The film generating product may be substance which only adheres to a support when applied thereto as a solution or emulsion, e.g. a copolymer of 85% vinyl chloride and 15% vinyl acetate, a butadiene-acrylonitrile copolymer having a molecular weight of 60,000 and containing 30% acrylonitrile, a ternary copolymer comprising 60% butadiene, 35% acrylonitrile and 5% styrolene, 75% vinyl chloride, 20% vinyl acetate and 5% maleic anhydride, or 75% vinyl chloride, 22% vinyl acetate, and 3% acrylic acid. The adhesive substance may consist of a natural or synthetic rubber, or rubberlike polymer, which may contain oils, derivatives of abietic acid, plasticizers, stabilizers, and pigments. The support may consist basically of plastic material, e.g. polyvinyl chloride, cellulose acetate, natural or synthetic rubber, or may be metallic or have a metallized surface.

The enclosure 1 may be defined by two parallel triangular or rectangular transparent sheets. In order to check angles, the enclosure is pivotally mounted on a backing sheet 9 which may be transparent. The enclosure 1 is pivoted about a shoulder 11 to the angle to be checked as measured on scale 15. The enclosure is locked in position by a wing nut and bolt arrangement Figs. 1 and 2 (not shown) or by a U-spring clip 23, 24 as shown. Thus when the base 10 is placed upon the surface to be checked, the liquid will align with line 5 (when in orientation shown) if the surface is at the correct angle i.e. at the angle set by scale 15. Other lines 6, 7 parallel to the other sides of a triangular enclosure may also be provided to allow any of the sides of a triangular enclosure to be abutted with the surface to be checked. A line 8 perpendicular to line 5 allows a check on perpendicularity. The liquid may be tinted paraffin and the enclosure may be of plastics material.

Title: Improvements relating to the manufacture of nitro-derivatives of aromatic amines
Filed: 1925-08-13
Abstract: 261,459. Leitch & Co., Ltd., J. W., and Everest, A. E. Aug. 13, 1925. Aromatic dinitrosulphonamides; dinitro-o- and p-toluidine, -aniline, and -p-chloraniline. - Aromatic arylsulphonamides in which the aryl radical is o- or p-tolyl, phenyl, or p-chlorphenyl, or the mononitro derivatives of such sulphonamides, are nitrated to yield dinitro derivatives which are treated with sulphuric acid to yield the corresponding dinitroamines; the nitration is carried out with excess of dilute nitric acid. According to an example, the mononitro p-tolyl derivative of toluene p-sulphonamide is boiled for six hours with two molecular proportions of nitric acid (18 per cent). The solid product, when dissolved in sulphuric acid and allowed to stand, yields dinitro-p-toluidine. which is purified from any mononitro-p-toluidine incidentally present by treatment with hydrochloric acid and sodium nitrite, the mononitro derivative being readily diazotized. Another example describes the nitration of the o-tolyl derivative of toluene-p-sulphonamide and the treatment of the product to yield dinitro-o-toluidine. Specification 6741/04 is referred to.
